IMPROVEMENT IN LUBRIGATOR.

...vnQ

Be it known that I, G. WATERS, of Cincinnati,'in the county of Hamilton,in the State of Qhio, have invented a new and useful-Improvement inSelf-Oilers; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference t-hereonmakingpart of thisspecification. v l i i i My invention relates to a method of graduatingthe discharge of oil from a, lubricator for shafting and machinery, vandconsists in providing the tubular conducting-stem or discharge-pipe witha straight, wedge-' shaped, or tapering-threaded screw or plug, having agroove or slot in its outside,which groove is made large at its bottom,and diminishing upward, and'soterminating at the top that'when the sameis screwed home, or as far into the top of the stem as it will go, itshall still not entirely close the orifice in the top of the tube,

for it is essentialrtoprovide against the liability or even possibilityof cutting off the supply of oil-altogether,

which results often in such disastrous consequences.

A means of nicely and finely graduating the ow of oil is much of adesideratum in very many placs; as, for instance, on the wrist-pin ofengine-cranks, where, in addition to the ordinary suctiou of rotatingbearings, we have the dashing or throwing-motion; as also on shaftingand machinery having a sharp vibratory motion.

In the accompanying drawings- Figure 1 is a view in perspective of mydevice, with reservoir attached.

Figure 2 is a vertical section of same, showing the screw or pluginserted about half Way intothe top of stem.

Figures 3 and 4.- represent vthe, detached graduating-screw, which isYthreaded upon its outside to t the orifice in topof stemyfig. 2, whichis tapped upon its inside.

In the`side of plug (figs. 3 and 4) isshown the slot or groove,mentioned above-,which may be made from the centre ofbottom, a, andterminating at z', at which point the screw is home, and the aperture in:op ot' stem for-passage of oil is very minute. l Y

A good practical size for an ordinary lubricator is represented in thedifferent parts in the drawings.

I claim' as new, and desire to secureA by Letters Patent of the UnitedStates- A lubricator, constructed with a graduating-screw or plug, inwhich is formed a gradually-tapering slot orl groove for regulating andcontrolling. the discharge ofroil, as described. g G. WATERS.
